Part 2. Nim in practice

Now that you know the basics of Nim, you’re ready to move on to writing some software.

In chapter 3, you’ll be developing a simple but functional chat application. This chapter will mainly teach you about asynchronous sockets, but you’ll also learn something about parsing and generating JSON, reading text from the standard input stream, and using Nim’s module system.

Chapter 4 focuses on the standard library, showing you usage examples of various algorithms and data structures defined there. It also offers a more in-depth look at the module system.

Chapter 5 looks at package management, which is extremely common nowadays. Package managers are useful because they offer an easy way to install third-party libraries for use in your applications.

Chapter 6 is about parallelism. This is an important topic as it allows for some powerful optimizations, especially in today’s multicore world. In this chapter we’ll look at a parsing problem that’s easy to parallelize. Different parsing methods are also demonstrated.

Chapter 7 leads you through the development of a significantly simplified Twitter clone. You’ll learn how a web application is created using the Jester web framework, how HTML can be generated using Nim’s filters, and how to store data in an SQLite database.
